Sage 100 ERP v4.3 PU 23: End user called reports that in AP they have paid an invoice twice - - which now results in a negative balance for the invoice. I login - can see what appears to be two separate check paid against the same invoice. By what magic is this possible?

Were they updated in the same journal?

You can overpay an invoice using Manual Check Entry.

They have two checks - claim that each was created through the regular invoice payment selection. The only thing I can think of is somehow the second was selected and updated before the first was updated.

Too many cooks in the AP kitchen!

You should be able to see if check type was Auto or MC to verify that.

wound up reversing the second check and that got them back into a good position. I've just never seen a double payment like that before - it did look like two computer generated checks and they were about 7 days apart. The only thing I can think of is that they didn't update the first check run and made a second though my memory is that if you do that the second over-writes the first check printing data and would not result in duplication.
